This is a great lab activity that consists of 12 stations. The lab sheet provided has questions for each station along with a picture of a different type of animal belonging to Phylum Porifera (sea sponges) or Phylum Cnidaria (Jellyfish, Hydra, Coral...). When I do this lab - I actually set out different specimens that correlate with the lab handout. If you do not have specimens to show students - it would also work to use pictures from the Internet or textbooks. This is a fun lab activity - that gets the students engaged! I have also included an answer key!
